Hi I'm new to poly. I've been with my bf for 8 yrs and he told me bout this site. I'm a very scared that if we let a female come into our relatioship that he will leave me for her. I've always been with one person nothing like this. But I am very attracted to females. He told me that the female will only be for me and just for him to cuddle with. What do I do? Can we make rules? Y do I feel like I'm being shared? Please help me.
